15	* attachment IDs or URLs. It prioritizes parsing for attachment IDs first. If no valid IDs are found, it will then
16	* attempt to parse for image URLs.
17	* Supported input value types:
18	* - A single attachment ID (integer or string) or a single image URL (string)
19	* - A comma-separated string of attachment IDs or image URLs
20	* - An array of attachment IDs and/or image URLs
